The University of Liverpool will lead a £1.7million AHRC award to make it possible for people to trace the records of Londoners sentenced to either imprisonment or transportation from 1787 up to the 1920s when the last convict died.

The First Fleet's 225th anniversary Herald Sun They arrived in Botany Bay on January 18 but despite praise from Sir Joseph Banks (who was on Captain James Cook's first great voyage of discovery, on the Endeavour 1768-1771) it was deemed unsuitable...
Some 40,000 to 50,000 years ago, a band of intrepid Southeast Asians became the first humans to reach Australia, and without a single glance at a GPS unit. Now new research suggests that perhaps 3000 people—many more than previously thought—made that foray into the unknown to become the continent's founding population and the ancestors of Australia's aboriginal people.
Indirect estimates based on carbon dating point to intentional settlement by a large population. At least 1,000 Aboriginal founders first arrived in Australia some 50,000 years ago, a reconstruction indicates — numbers that could be evidence of an intentional migration rather than the accidental stranding of a few individuals at a time. The study also finds that the population was devastated during the latest Ice Age, but later rebounded.
The prehistoric settlement of Australia has long been considered a simple story: a founding group of 150 people or fewer made it to the Australian mainland 50 millennia ago and grew to no more than 1.2 million by the time European settlers arrived in 1788. Debate focused on whether the founding population grew immediately after colonization or boomed later, in the past 5,000 years.
To tease out a demographic signal from the past, Alan Williams, an archaeologist at the Australian National University in Canberra, amassed the most comprehensive radiocarbon data set ever put together for the continent, from both published and unpublished sources. He analysed the dates of 4,575 artefacts from 1,750 archaeological sites.
Applying methods that others had developed to analyse a similar dataset from North American artifacts, Williams graphed the number of data points for each 200-year period, and made the assumption that for each given area, changes in the number of data points from one period to the next were a good indication of changes in population size — while correcting for the fact that some types of archaeological site can be lost over time owing to processes such as erosion. Assuming that the population would be between 750,000 and 1.2 million by the eighteenth century, he fit a smooth population curve to the data.
According to Williams' curve, 1,000–2,000 founders would be necessary to reach the population that was in place when the Europeans arrived. After the founders arrived, the population would have stabilized at low levels, but crashed during the most recent Ice Age, around 20,000 years ago. “To quantify the impacts of the last glacial maximum — and see a 60% reduction in population — is quite horrendous,” says Williams. After the Ice Age, population growth rates began to increase in pulses, starting 12,000 years ago.
